Notes on 500 user VM configuration

This is a minimal VM configuration for use with Cisco Hosted Collaboration Solution.

Maximum capacity:

500 Full UC users

1000 IM-only users

6 single nodes or sub-clusters

This VM size can be used when performing a DRS migration from a non-virtualized/physical server with a disk capacity of 80 GB or less (e.g. MCS-7825-H2).

If you are migrating from a physical server with more than 80 GB of storage space to a virtual machine with a user deployment size of either 500 or 2000, see the Disaster Recovery System Administration Guide for more information.

2000 IM-only users

This VM size can be used when performing a DRS migration from a non-virtualized/physical server with a disk capacity of 80 GB or less (e.g. MCS-7825-H2).

Notes on 2000 user VM configurations

Maximum capacity:

2000 Full UC users per node

2000 IM-only users

3 single nodes or sub-clusters

This VM size can be used when performing a DRS migration from a non-virtualized/physical server with a disk capacity of 80 GB or less (e.g. MCS-7825-H2).

If you are migrating from a physical server with more than 80 GB of storage space to a virtual machine with a user deployment size of either 500 or 2000, see the Disaster Recovery System Administration Guide for more information.
